Geometry parameters of the metamaterial unit cell. 𝑎=140𝜇m, 𝑤=15𝜇m, 𝑔=4𝜇m, and 𝜃=22.5^∘. The metamaterial consists of gold (Au) crosses on top of a BCB film. (b) Distribution of charges (+,−) and currents (arrows) at resonance when excited by a horizontally polarized incident THz wave. (c) Microscope image of a fabricated metamaterials [44].
